Let S be the sample space.
| Then, n(S) = 52C2 = |
(52 x 51) |
= 1326. |
| (2 x 1) |
Let E = event of getting 1 spade and 1 heart.
| ∴ n(E) |
= number of ways of choosing 1 spade out of 13 and 1 heart out of 13 |
|
= (13C1 x 13C1) |
|
= (13 x 13) |
|
= 169. |
| ∴ P(E) = |
n(E) |
= |
169 |
= |
13 |
. |
| n(S) |
1326 |
102 |
